论文摘要
我们研究喷嘴几何形状对流下垂直圆柱纤维的薄流体膜动力学的影响。最近的实验表明，变化的喷嘴直径会导致胶片中不同的流程度和液滴特性。使用加权残留建模方法，我们开发了一个耦合方程式系统，该系统可以解释惯性，表面张力效应，重力和膜稳定机制，以描述近乎插头的流体结构和下游珠珠动力学。我们报告了预测的液滴特性与实验数据之间的良好一致性。
We study the effects of nozzle geometry on the dynamics of thin fluid films flowing down a vertical cylindrical fibre. Recent experiments show that varying the nozzle diameter can lead to different flow regimes and droplet characteristics in the film. Using a weighted residual modeling approach, we develop a system of coupled equations that account for inertia, surface tension effects, gravity, and a film stabilization mechanism to describe both near-nozzle fluid structures and downstream bead dynamics. We report good agreement between the predicted droplet properties and the experimental data.
